Abstract: A method and an apparatus for winding a yarn package, wherein an advancing yarn is reciprocated by means of a traversing yarn guide within a traverse stroke, and deposited on the yarn package. To avoid high package edges, the traverse stroke of the traversing yarn guide is variable in its length within the width of the yarn package during the winding operation. The length variations of the traverse stroke occur during the winding cycle by a predetermined stroke modification function, which is determined from a mass distribution of the yarn on a hypothetically wound, ideal yarn package, so that it is possible to produce a predetermined package density of the yarn package.

Abstract: A control system for a motorized freight elevator landing door in which all of the doors in a single line of a hoistway are controlled with one set of proximity sensors carried on the elevator car. The sensors signal a controller that operates electric motors for opening and closing the landing door where the car has stopped. The door operating motors are two speed units and the sensors and controller are arranged to operate the motors at high speed during most of the travel in opening or closing movement and at reduced speed at the end of movement. The controller applies power to the motor for a short period after the door is fully closed or open to stall the motors and thereby dampen any rebound motion.

Abstract: A versatile core has a tubular body with opposing ends and includes a circumferential wall for receiving the sheet roll. A plurality of circumferentially spaced apart crush ribs project radially inward from the annular inner surface and extend axially between the ends for nesting in corresponding slots in the spindle. The crush ribs are defined by a plurality of cut outs, which are provided at each of the opposing ends and are defined by the circumferential wall. The cut outs accept and engage various configurations of ribs of a spindle assembly, with the ribs of the spindle located between the crush ribs of the core. The exterior surface of the tubular body may have a texture selected to provide the desired adhesion between the tape (attaching the sheet roll to the core) and the body surface of the cylindrical body.

Abstract: A cord retractor device provides multiple retracting mechanisms for independently retracting cords in each of the retracting mechanisms while operating the mechanisms in unison. The retracting mechanisms may be ganged together to form a multiple cord retraction mechanism. The retracting mechanisms may be ganged through the use of magnets, adhesives, screws or other suitable coupling agents. The cord retractor mechanism may be provided to permit the insertion of a cord externally in a retrofit option. The retractor mechanism housings may be shaped to depend upon where each mechanism is ganged together, such as in an outer or middle configuration. The ganged cord retractors contributes to preventing cord entanglement while increasing the safety of the cords in a mini blind application.

Abstract: Comminuted carpet pieces are fed to a first stirred tank together with an aqueous solution containing separating salt, to form a first suspension, which is fed to a first mechanical separating stage. A first high-solids phase, a second high-solids phase containing polymer fiber material, and a liquid phase are obtained therefrom. The second high-solids phase is mixed with a water-containing separation solution in a stirred tank, to give a second suspension, which is fed to a second mechanical separating stage.
